What are the risk factors for Alzheimer's disease?

The strongest evidence so far points to age and family history. Increasing age is the greatest known risk factor-about 10 percent of people have Alzheimer's by the time they reach age 65, and nearly 50 percent are affected by age 85. Alzheimer's strikes individuals from evey walk of life, every ethnic groups, and every walk of life every ethnic group and every income level.

Family history is another predisposing factor. Having a parent or sibling with the disease increases an individual's chances of developing Alzheimer's. Scientists have found one gene that rises Alzheimer's risks as well as several faulty genes causing rare forms of the Alzheimer's that tend to occur before age 69.
